So I've read that the official size of the playing field is 3'x6' which is fine,

For X-wing/armada/Imperial Assault there is a subculture where people are able to Print gaming mats to play these games on. Is there such a source to print something out like this for legion? Desert, Meadow, Iceburg mats would all be awesome. I can find stars and nebulas in high resolution a plenty on the internet but seem to struggle looking for similar style artwork to print for this game.

Anyone able to help? I can buy a mat from Russia for twice what I can get Printi to print one and get it in half the time, but I'm unable to find a suitable image.
